Answer:
12.77 miles per hour
Step-by-step explanation:
Step 1
Convert the diameter from inches to feet
Your bike has a wheel diameter of 29 inches.
1 inch = 0.0833 feet
29 inches =
29 × 0.0833 feet
= 2.41667 feet
Step 2
Circumference of the tire = πD
= π × 2.41667 feet
= 7.5921927182 feet
Step 3
The number feet traveled per hour is
148 revolutions per minute × 7.5921927182 feet
= 1123.6445223 feet per minute
60 minutes = 1 hour
Hence,
1123.6445223 × 60 =
67418.671337 feet per hour.
Converting from Feet per hour to Miles per hours
1 mile = 5280 feet
= 67418.671337 feet per hour/5280 feet
= 12.768687753 miles per hour
Approximately = 12.769 miles per hour
: 1,2,4,5,10,20
